Emerson Corporation (NYSE: EMR)'s business brand, Emerson Industrial Automation subsidiary - Branson Ultrasonics (Below), unveiled the SNEC 2011 International Solar PV Exhibition and launched its portfolio of solutions for the photovoltaic industry, including Amorphous silicon photovoltaic cell welding solution, and a series of cleaning solutions for the silicon, silicon, solar cells and battery components in the photovoltaic industry.
The new energy industry has become the focus of global attention. As an inexhaustible solar energy, solar photovoltaic power generation is also receiving more and more attention. With regard to this development trend, the MWX100 ultrasonic metal welding machine launched by Benteng is mainly applicable to the welding of amorphous silicon solar cells. Ultrasonic energy generators are used to transmit high-frequency vibration energy from the welding head through the transducer and amplitude modulator. The amorphous silicon glass plate and the aluminum ribbon metal surface make the aluminum ribbon metal surface and the amorphous silicon glass plate surfaces vibrate and rub each other to form fusion between molecular layers, thereby achieving the effect of welding. The entire welding process can be precisely controlled, and at the same time, since the welding process is performed at a low temperature, the material will not be deteriorated due to overheating, and the welding firmness will be affected. Because there is no need to add flux, the welded panel has good conductivity and the resistance does not change substantially. The welding machine adopts the optimized multi-functional frame assembly design. The flexible frame assembly can realize spot welding and continuous seam welding welding processes, and can be adapted to the desktop manual operation and automatic assembly line production and processing. In addition to the solar photovoltaic industry, it can also be applied to other new energy industries, such as the lithium battery industry (including new energy automotive batteries).
Complementing the ultrasonic metal welding solution is a series of cleaning solutions launched by Benteng for the photovoltaic industry in the production process. Whether it is single crystal silicon, polysilicon or amorphous silicon, multiple processes in the production process require a cleaning process, and the requirements for different cleaning processes are also different. This includes silicon cleaning before silicon ingot ingot, pickling after silicon ingot grinding, pre-cleaning after ingot slicing, precision cleaning of silicon wafer and silicon wafer in wafer box, solar energy The battery is cleaned before texturing, particle cleaning after CVD (chemical vapor deposition), etc. The Quadrasonic multifrequency ultrasonic generator from Branson can provide up to four cleaning frequency (40kHz, 80kHz, 120kHz, 170kHz) options to meet the cleaning requirements of different processes. The equipment can be used alone to connect the cleaning tank, or it can be integrated into the cleaning automation assembly line system. It also has many functions such as adjustable power and frequency scanning, which can provide fast and uniform according to different requirements in the photovoltaic production chain. And high-quality cleaning effect.
In addition, the 9500 series of megasonic generators demonstrated at this exhibition is Benteng's latest high-performance cleaning generator. The megasonic waves generated by the product are transmitted to the water through megasonic jets, megasonic nozzles, and megasonic plates, allowing the water molecules to vibrate at an acceleration of 105G, using megasonics to remove tiny particles with a surface area of ​​less than 0.2μm. Megasonic cleaning equipment equipped with 9500 generator is the best choice for cleaning flat glass and silicon wafers.
Today, energy conservation and emission reduction are deeply rooted in people's minds, and the low-carbon economy is developing rapidly. In this context, as an industrial leader in the field of ultrasonic welding and cleaning, Benteng will also accumulate deeper technology and promote the development of ultrasonic applications in the field of new energy.
Plastic Chemical includes eco-friendly Pvc Plasticizer, e.g. Epoxy Fatty Acid Methyl Ester (EFAME) and Epoxidized Soybean Oil (ESO), and other plastic chemicals. They are mainly used to replace the primary plasticizer in PVC products, like the DOP, DINP, DBP, DOTP, ATBC, and other plasticizer. The plastic chemical is made of plant oil, and has excellent compatibility with PVC resin. It will help improve the physical properties of the product and prolong the aging time obviously.
